The only way to be truly fair with admissions is to admit blind of any defacto discriminatory identity/categorization method and based entirely on competency and scores. I realize that is unpopular for a variety of reasons, but are elite academic institutions meant to be elite academic institutions, or are they social engineering laboratories?
They are meant to educate students for success in the world, and success for the world. Of course they are social engineering laboratories; that's in their charters.
